CFC substitution, who is going to divide the market

follow to suspend the cost to the deadline of the ozone layer material to produce and use day after day near to us, take material instead of ozone layer, especially the freon refrigerant, more and more become a attractive piece of 'cake' in the shopping mall.

in 1987, 'to take the ozone layer material ( ODS) Signing of the Montreal protocol in Canada to take effect. Big bag yesterday nearly 20 years, now has 188 countries signed the government agreed to perform the convention designed to protect the earth's ozone layer world environment. The Chinese government in June 1991 after signed the Montreal protocol, drew up the ODS yield and cost of frozen policy, in the relevant state department recently proposed freon refrigerant ( 氯氟化碳) Specifically for China to accelerate the screening program, on July 1, 2007 to suspend the first fruit of ODS and costs, to ensure that in 2010 the completion of the performance guideline. Refrigerator, air conditioning, automotive air conditioning now mostly in applying CFC refrigerants of ODS screening material, the Montreal protocol rules contains 15 kinds of CFC, three kinds of halon, 40 kinds of as, 34 kinds of HBFC, carbon tetrachloride and methyl chloroform and other damage to the ozone layer has a substance. Especially in the meantime of CFC has the greatest effect in the screening of human now days, because the CFC is widely used in refrigerator and refrigerants in air conditioners. According to the material, by the end of 2003, China's urban household refrigerator has reached 88 per hundred households. 7. Rural household refrigerator has the amount has reached 14 per hundred. 8 units. The development of air conditioning are also the same to the first half of this year, 90 million sets of Chinese households have air conditioning has broken, and there are about 1. 5 million commercial air conditioning in use. Cars followed the sharp increase in car air conditioning is rapid to add, according to the Beijing traffic administration, Beijing car arrived in 1 million, the total for 48 years, but from 1 million to 2 million, took six and a half years. Private vehicle ownership in Beijing now has surpassed 1. 65 million, and two family plan two years to buy a car. Beijing is a microcosm of the whole country. Experts speculated that Chinese car demand will surpass 5. 5 million vehicles in 2005, by 2010, China has the capacity will reach 100 million cars. In the refrigerator, air conditioning, automotive air conditioning, 2002 years ago the factory goods, most use CFC refrigerants, will be replaced before the performance period. And the fruit in the refrigerator, air conditioner, the more will leave a lot of CFC substitutes. Two categories of CFC substitutes cutting format signed the Montreal protocol, the world development and comparison, some developed countries and regions through on CFC substitutes, gradually form hydrogen fluoride hydrocarbon refrigerants and hydrocarbon refrigerants two categories of goods. Widely used in the United States, Japan and other countries in the former, the latter in esteem by European countries. Both ozone layer damage factor ( ODP) All is zero, not cause damage to the ozone layer. In the form of global warming greenhouse effect coefficient ( GWP) Hydrocarbon, hydrocarbon is significantly lower than that of hydrogen fluoride products. Dissolve in water, condensation pressure, evaporation pressure, exhaust temperature and vacuum degree on request and system target aspects, such as capital, hydrocarbons than hydrogen fluoride hydrocarbon products has great advantage. But hydrogen fluoride hydrocarbon goods in the commodity flameproof explosion-proof safety and habits are now in use of equipment, etc have their own advantages. In September last year, the state environmental protection administration issued the Chinese ozone consuming material substitute for recommended directory ( The first) , these two types of CFC substitutes are listed, the market 'pass'. China of CFC substitutes, after a long effort, now the two types of substitute have constituted must develop and produce ability. Based on HFC - 134 a as a representative of hydrogen fluoride produce hydrocarbon refrigerants, under the auspices of the world environmental protection fund, after for some of the original production of CFC refrigerants from factory to transform, this kind of CFC substitutes made a major break in capacity, the largest production equipment will have reached 5000 tons/year. Now the first applied to household appliances, cars, commercial and industrial refrigeration category. Another type of isobutane ( R600a) Produce hydrocarbon refrigerants, represented by its production factory has a more lucrative oil processing vice material capital goods, the largest production equipment can reach 2500 tons/year, at the mercy of first applied to household appliances refrigeration category now. Success up to now China has developed a variety of CFC substitutes of production technology and technology, can produce identity in the world's first CFC substitutes. Its product performance has reached the world similar specification goods, broke the began to such imports on the domestic market has a control place situation. CFC substitutes for remains to be a 'fist' looking to China's development of CFC substitutes, although has now begun to take shape, but to occupy the domestic market, all in the world market competition, on the development and produce goods to sell, there are some significant distance, especially in the full use of China's rich hydrocarbon material capital, CFC substitutes to constitute appropriate China produces operating the 'fist', also need to further efforts. In the refinery of jinling petrochemical company is China petrochemical system earlier emphasis on CFC substitutes 'cake'.
